Application led October 12, 1927.

The object of my invention is to provide a sail boat of simple and novel construction, particularly designed for speed and for safety when travelling at high speed.

F or accomplishing the abovepurpose, it is my further object'to providein connection with a. sail boat, a pair of laterally spaced stabilizers in the form of members substantially lighter than water and vadapted to travel on or in the water depending upon the position of the boat.

-Another object is toprovide means for supporting said stabilizers from the hull of the sail boat including preferably pivoted arms and to provide means for adjusting the stabilizers and said pivoted arms for varying the position of thestabilizers with relation Vto the boat.

Still a further purpose is to provideV such stabilizers with upper air compartments and with lower compartments adapted to hold water, which lower compartments are provided with valves lcontrollable from the deck of the sail boat.

Another purpose of my present invention is to provide a bowsprit for the fore sail and means for securing the bowsprit either extended forwardly from the mast or laterally therefrom. j

Still another purpose is to provide in such a sail boat, a novel braking or retarding means for slowing the speed of the boat quickly where such slowing down is necessary. Y

Although the invention is susceptible of a variety of embodiments, it is unnecessary to fully describe and illustrate more Vthan one Vin order to givea full understanding ofthe invention both from its structural and functional standpoints.

YVith these and other objects in vieW my invention consists in the construction, ar- .Y rangement and combination of the various parts of my device, whereby the objects contemplatedrare attained, as hereinafter more p fully setforth, pointed out in my claims and illustrated in the accompanying drawings,

in which:

Figure l shows a top or plan view ofthe sail boat embodying my' invention.l

Serial No. 225,696.

Figure 5 is a detail sectional view talren y on the line 5-5 of Figure 2.

Figure 6 is a detail sectional view talren on the line G-6 of Figure 1.

Figure 7 is a sectional view taken on the line 7 7 of Figure l showing one of the stabilizers inv rear elevation and part of the sail boat hull in section; and

Figure 8 is an enlarged sectional detail view of the lower part of one of the stabilizers, illustrating the construction of one of the controlling valves therein.

ln the accompanying drawings, I have used the reference numeral l0 to indicate rihe boat may if desired, be provided with a center board l2. lt also has the usual rudder lll. The hull lOand the stabilizers hereinafter more fully'described, are so constructed and proportioned that normally the body of the boat and the front ends of the stabilizers, rest high in the wat-cr as illustrated in Figure 2 where the water level is indicated at 16.

The sail boat has the usual mast, main sail 20, top sail 22, flying jib and fore sail 2G. Y The pulleys and tackle for the sail are illustrated more diagrammatically because they do not in themselves forni a part of `my present invention except as hereinafter more fully set forth.

, My sail boat'is intended for fast sailing and the hull is therefore relatively narrow. On cach side of the sail boat- I provide stabilizers which are indicated'generally by the reference numerals 28.

Each stabilizer consists of a hollow body having generally the shape of a boat. The body of each stabilizer 28 has an interior horizontal partition 30. Above the partition is an air tight compartment 32 for giving the stabilizer' ample buoyancy.

On the top or decl; of the stabilizers 28 are brackets 34 to which are journaled the pivot members 36. The members 36 are downturned from rods s() which are pivoted to the hull l0 as at l2 and extend laterally as shown in Figure 1. AF or each stabilizer there aretvvo of the pivoted rods 40.

` rods 40 are arched upwardly as clearly illustrated in Figure 6 of the drawings to be well above the waves so that they do not impede the progress of the sail boat. Suitable braces 56 and 58 are provided to lend rigidity to the rods 40.

ln the bottom of each stabilizer 28 is a -pair of hinged doors or valves 46.` rlhe are controlled by hand wheels 66.

-68 ofthe stabilizer.

'lizer.,

yhinges 52 for thefdoors 46 are of the Yspring type so that the doors are normally closed by the springs. Tubes 48 extend through the paititionBOand deck 28 of. each stabi- Secured to cach valve or door 46 is a con-` trolling` lever 50 which when moved tothe dotted line position (F ig. 8) will open the door `46. Suitable gaskets 54 are provided for forming a water tight joint when the doors are closed. A stop arm 96is provided on the door 46 to limit the amount of its opening movement. Y Y

Cables 60V and'621are secured to the outer ends of the levers 50 and extend up through their respective tubes 48. i rfhe cables 6() and 62 extend from the tubes 48 toward the hull 10 and are'secured to cable drums 64 which From the foregoing description it will be obvious that by adjust-ing the cables 60 and 62, the valves or doors 46 may be opened or closed as desiredr for admitting-- water to or allowing it to drain from the lower compartment clearance around the cables 60 and 62 within the tubes 48 to allowfree flow of air `into yand out of the :lower .compartment of the stabilizer to take the place of water flowingV outwardly through the doors 46 or to be 'displaced by water flowing inwardly through too gre-at careening of the-sail boat.

It will be noted that l have provided two valves 46 in each stabilizer 28. The forward valve 46 opens downwardly and forwardly while the rear valve opens downwardly and rearwardly. By this arrange.

ment the valves y46V maybe manipulated Y to assist in filling or emptying` the ,comparteV4 "nient `68 of water.

Y For instance when the forward valve is opened it will scoop water up: intoY the stabilizer and whenk the rear valveis opened the stabilizer will `bequickly emptied of water even with the door drag- ',ging in the water lovervi which the boat is sailing. y

-V :The stabilizers function in two ways. lFor. instance, if the sail boat is turning to the There is sufficient i right, the right hand stabilizer may be left empty of water'and its buoyancy will thereby lessen the tilting of the hull 10. The skipper Awill know of his purpose to turn to the right and-will at the proper time have .opened the forward valve 46 of the left hand stabilizer and allow that stabilizer to take `water `into the compartment 68. rlhen in making a right turn, the weight of the stabilizer will also contribute to causing the hull 10 to maintain its equilibrium.

It will `thus be observed, that the stabilizers may be adjusted to different positions and that their buoyancyT and weight may be controlled by the skipper in such a manner as to give him a control of his sail boat whichwould otherwise be impossible.4

lBy using these stabilizers, the weight of the boat may` be greatly increased, the handlingof the boat will be greatly facilitated and safety in handling it will be substantially increased. This is of considerable importance in speed boats and those used for racing, `because it stabilizes the sail boat in heavy. breezes and facilitates the rapid maneuveringof the boat.. Y

For greatly increasing the speed of such sail boat, I providev the ,following means. The bowsprit Oyis pivoted to the mast 18 in the usual way and, ofcourse, normally .projects forwardly beyond the bow Yof the boat. Near the bow of the boat it rests in a block 72 and is securely locked there by,

means of a pin 74 projected through suitable holes in the upstanding arms 72'L1 of theV block .72 above the bowsprit. Y

l provide similar blocks 72 on the deck of the hull 10 on thev left and on the right of the mast 18 so'thatby removing the pin 74, the howsprit maybe-lifted from the forward block 7 2 and rested in either the Vright or left` end block' 7-2 as Yillustrated. for eX- ainple by dotted linesy in Figurel.

By swinging the foro sale in onedirection of thcrboat and the main sail almost in the oppositeV direction of the boat, the boat can be sailed almost directly beforethe wind.

rEhisis made possible'by the arrangement for vsecuring-the bowsprit, for insta-nce, in'

l have provided another ineans for facili- Y tating quick maneuvering ofthellboat and for slowing` it down quickly. Figures 1, 2 and 4, it will be noted that there is provided rearwardly of the center board ByV referring to 12, a brake V,which is built much like the ordinary centerfbcard.

In the hull` of the sail boat 101 provide a well 76st the usual kind. provided for center boards. Slidably mounted for vertical reciprocation in the well 76 is a brake member 78 built very much like an ordinary center board. On the front face of the upwardly projected board 78, l provide a toothed rack bar SO.

Suitably journaled in brackets S2 and 84 on the frameoil the well 7 6, is a shaft 86 on which is a crank handle 87 (in Figure l). On the shaft 86 is a pinion 88 which meshes with the rack bar 80. One of the brackets Se carries a pivoted pawl 9G coacting with' the pinion 88.

In case it is desired to quickly yslow the boat down, the pawl 90 is thrown out of en gagement with the pinion 88 and the crank handle 87 may be manipulated for rotating the shaft't 8G and the pinion 88 for lowering the brake 78. The brake 78 when lowered into the water, will quickly impede and reduce the speed et the boat.

rlhe brake is used in approaching a dock or in making a sharp turn around a buoy or wherever the handling of a boat may make the use of the brake advisable. lt will thus be seen, that l have provided a sail boat which on account oic the features ot structure herein described, can carry more sail than is otherwise possible and therefore, have greater speed.

l have provided means tor providing an'iplesa'lietyin such a boat. l have also provided means as nereinbeiiore described, which makes the maneuvering of such a boat easy and rapid.

lt will be understood that changes may be made in the details of the construction and arrangement ot the parts 'oi my improved sail boat, wit-hout departing from the real spirit and purpose of my invention.

Grdinarily the stabilizers 28 draw about sizrinches of water when the hull l0 is on an even keelu rThis arrangement could be changed according to the size of the boat and according to the conditions under which it is to be used.

l have, for instance, shown suitable rubber gaskets 54 around the valves or doors d6.

y Any suitable gasket may be employed and the forms of these valves might be greatly modiiied. I y

lt is my purpose'to cover by my claims any such modified forms of structure or any use or" mechanical equivalents which may be reasonably used within my claims.

I claim as my invention: f
